Question

A homogeneous block, with height ℎ and width ?,
is in static equilibrium on an inclined plane, see figure. The angle between the inclined plane and
the horizontal plane is ?. The static friction number
between the block and the substrate is ?S. A force ? ⃗
acts on the block, in the direction parallel to it
inclined plane (see figure). The magnitude of the power
? ⃗ is such that the block tends to tip. Draw
a correct exposure of the block.
